Considering it was $20 cheaper on like Monday, I will pass for now.
Yeah, it was unfortunate timing for this thread; I wish I'd opened it with the current price in play. No one likes a price increase. It just kills me when gas goes up a dime, even tho that's only a buck fifty at the pump on my old coot's car.
And I am a big fan of the Analox EII CO portable unit as well as the company's dedication to serving divers, more so than pleasing agencies. You certainly can't go wrong there. It costs twice as much and with the GBPound gaining on the USDollar, it might go up too - but it's still a great investment in safe diving.
:laughing: When I first got interested in tank testing and eliminating this risk, I really wanted to use a battery powered home monitor. Loved the price, and I am cheap, but they are not even in the ballpark for serving our needs. I carry one in my car and for hotel rooms. It gets baked when I park in the Texas sun for an afternoon and I have had to send it back for replacement once, but the company was nice about it. There are better units for cars so maybe I'll talk myself into springing for one?
I use a couple of AC/DC units at home, one also monitoring for natural gas leaks.
The first unit I tried was the Pocket CO, and it's still available for $125 on some sites. It can be used with freezer quality ziplock bags for tank testing, I've done it many times - but it is a hassle, the unit has a lot of shortcomings - especially in cross contamination, and mine failed last time I tried to calibrate it so I decided against replacing the sensor.
$159 vs $179 for this Inspector unit with Scuba tank adapter is indeed a $20 surprise, but honestly - not a significant problem if you want to guarantee safe tanks. If you want to keep it as cheap as possible tho, you could get the $149 basic unit, then make your own tank adapter as fully described in the other thread linked in post #1. It's a pretty impressive general purpose detector as well and I am tempted to get one of those! The more general US news I read about Carbon Monoxide, the more it seems we're discovering - injuries & deaths in all sorts of normal activities: boating, camping, driving, cafes, etc. I haven't done any caving in years, but if I did - I'd want to carry some monitor. Ok here it is for $145 & free shipping:
